(Master thesis, 2017)This thesis is written on the subject of marine towing operations. The purpose of the thesis is to identify and discuss technical challenges related to towing operations with respect to safety and operability. In addition, ... -
Analysis of current ROV Operations in the Norwegian Aquaculture - Reducing Risk in exposed Aquaculture Operations
(Master thesis, 2017)The Norwegian aquaculture is already considered to be one of the most dangerous occupations when it comes to risk, and the risk is likely to be amplified as the industry wants to expand and utilize more exposed areas. These ... -
Assessment and Numerical Simulation of Subsea Equipment Installation in Deep Water using a Fiber Rope Deployment System
(Master thesis, 2017)The past decade has shown a fast growing subsea production market tending to complete factories on the seabed involving even more complicated infrastructure, increasing size and weight of components to be installed. Deep ... -
Assessment and Numerical Simulation of the Pendulous Installation Method in Deepwater
(Master thesis, 2016)The final frontier of the oil and gas industry is considered by many to be deepwater fields (1500 m - 3000 m). With the recent fall in oil prices, the industry has however seen many deepwater projects postponed as a result ... -
Assessment of Pipeline Integrity after Trawling Impact by Investigating Dent with Gouge
(Master thesis, 2016)Mechanical damage from trawling gear interference amongst others cause a significant amount of damage to pipelines. The present study has done a review of current standards and recommended practise for assessment methods ... -
Automated Optimization and Design of Mooring Systems for Deep Water
(Master thesis, 2016)This master thesis focuses on automated optimization of mooring systems at deep water. The optimization work is based on the mooring system of the deep draft semisubmersible DEMO2000 developed by Statoil. This is a ... -
Control System for ROV Minerva 2
(Master thesis, 2018)This thesis cover the development of the motion control system for a Remotely Operated Vehicle (ROV). The Norwegian University of Science and Technology are receiving a new ROV, Minerva 2, which is the topic of this thesis. ... -
Design and Analyze of a Pressure Vessel for an Underwater Remotely Operated Vehicle Produced by Injection Molding
(Master thesis, 2016)BluEye Robotics aims to create a mass produced remotely operated vehicle for the consumer marked, that can be used in all parts of the world. For the next generation prototype they want the possibility of mass producing ... -
Design and Automated Optimization of Mooring Systems for Shallow Water and Harsh Environments
(Master thesis, 2016)The present market places significant cost pressure on the design of a mooring system. It is there- fore important to be able to produce a mooring system at the lowest possible cost, and at the same time, to ensure a safe ... -
Detailed Design of a Thruster Solution for a Small Mass-Market Remotely Operated Underwater Vehicle
(Master thesis, 2016)This thesis addresses the design of a thruster-solution for a mass-market Remotely Operated Underwater Vehicle with respect to performance and cost while increasing reliability, efficiency and durability of the system. With ... -
Dynamic Simulation of Module Installation on Deep Water
(Master thesis, 2015)The Aasta Hansteen field is a gas field outside the coast of Northern Norway. Production is planned to start in 2017. The gas field is situated at 1300m water depth the deepest on the Norwegian continental shelf. During ... -
Efficient Installation of Subsea Equipment in Deep Water
(Master thesis, 2018)This thesis presents methods to preform subsea equipment installations, and highlights problems related to the conventional crane operation used in marine operations. The crane operation faces many challenges at water ... -
Feasibility of Deep-Sea Mining Operation Within Norwegian Jurisdiction
(Master thesis, 2016)Numerous hydrothermal vent sites are discovered along the Arctic Mid-Ocean Ridge (AMOR), stretching some 1,050 km from Jan Mayen to Svalbard, mostly within Norway s economically exclusive zone (EEZ). Associated with these ... -
Installation of Subsea Equipment Protection Covers - Establishment of Operation Limits and Assessment of Operability and Weather Windows
(Master thesis, 2017)The oil and gas industry has become more challenging the past years and marine operations must be performed in smarter and more cost-effective ways. Waiting on weather should be minimised and design and planning will be ... -
Numerical Investigation of 3D Flow Around Two Tandem Cylinders
